PENCIL-SHARPENER.

Application filed December as, 1917.

ALLEN and JOHN CLIFFORD MAUGANS, both citizens of the United States, andresidents of the city of New York, borough of Manhattan, in the countyand State of New York,

have invented a new and Improved Pencil- Sharpener, of which thefollowing is a full, clear, and exact descriptlon.

Among the principal objects which the present invention has in v1ew are:To provide a reservoir for the dust and other waste produced whensharpening a pencll; to provide a fixture havingrenewable sharpeningexposed surfaces; to furnish 111 a single apparatus, a plurality ofsharpening surfaces; to furnish an. apparatus Wlth sharpening membersrelatively graduated as to rapldlty of operation; and to simplifyandreduce the cost of construction.

Drawings Fig. 2 is a vertical longitudinal section thereof Fig. 3 is avertical cross section showing a fragment of the apparatus, the sectlonbemg taken as on the line 3-3 in Flg. 2;

Fig. l is a perspective View in sectlon of a modified form of theinvention.

Description As seen in the drawings, the apparatus is comprisedprimarily of a box body 8 and a cover 9 therefor. The dimensions of saidbody and cover may be varied. It is preferred, however, that theapparatus shall be diminutive to adapt it for pocket use, 1f desired.

. Preferably the body 8 is provided with a wood-removing cutter 10.

shown in the drawings, has a funnel-shaped body, which supports inservice relation an interiorly-extended knife 11. The knife 11 serves toremove the wood from the lead or the marking portion of a pencil whenthe same is inserted within the funnel body 10 and turned while beingpressed against the edge of the knife 11. The shavings removed by-the'knife 11 are delivered through the side wall 12 inthe cutter 10 anddeposited in the bottom of the body 8.

The cover 9 is provided adjacent the ends Specification of LettersPatent. I

thereof, with spring-like supporting sections 13. The sections 13 arepreferably formed by severing the portion thereof adjacent the ends ofthe cover,

sive 15 is introduced. The sections 13 are also removed at-ithe forwardedge thereof from a central bridge portion 16 integrally connected withor rig dly attached to the cover 9, the intervening space being providedfor the abrasive 15, the edges whereof are in. service extended beneaththe bridge 16, as shown in Fig. 2 of the drawings. The resiliency of thesheets of abrasive 15 is relied upon to give the necessary pressure toremove the lead of the pencil when drawing the same to a point. If thelead or point of the pencil is not inserted completely under the'bridgeportion 16, it will be understood that the refuse or lead filings lefton the sheet of abrasive will flow into the box for deposit on thebottom of the body 8, when the sheet of abrasive is depressed as shownbest in Fig. 2 of the drawings.

As indicated in Fig. 1, two characters of abrasive are preferablyemployed, one being coarser than the other. One or more layers of theabrasive strips are employed as shown in the drawings, where two layersare indicated.- It will be understood that if desired, arrangements maybe made for employing an increased number of sheets.

When introducing the abrasive sheets in active position in connectionwith the top 9, it will be seen that the two sections ofthe sheetscooperate, the one having its edge under the bridge 16 forming ananchorage or resistance for the resilient exercise of the other ortionsof the sheets for holding the unused portions of the said sheets againstthe sides of the cover 9. This arrangement permits the easy introductionof the body -portion 8.

, shifted to present new or fresh surfaced sections. To do this, thecover 9 is removed from the body 8 when it will be found that theabrasive strips orsheets are readily accessible.

'It will be understood that while I have herein shown an abrasive in theform of sheets of sand paper, it will be obvious that any suitable formof abrasive, either thus producing a slot 14,

' through which the unused section of an abrabody to engage the ends ofsaid sections .to

stance is attached to the box body or tothe bridge 16 thereof.

In the modified form shown in Fig. 4, the abrasive 17 is rigidlyattached at one edge to one side of the box body 8, with a bridge 18 atthe opposite side to prevent the lift of abrasive above the box level.

Claims:

1. A pencil sharpener comprising a boxlike body; a plurality of sheetsof abrasive bent to form angularly'disposed sections, one of saidsections being disposed in covering relation to said bo y; and means forsupporting said covering sectlons, said meansembodying cross membersextending,

across said body, one of said members forming a bridge disposed at thecenter of said prevent the lift thereof above the level of said body.

2. A pencil sharpener comprising a boxlike body; a plurality of sheetsof abrasive bent to form angularly-disposed sections,

one of said sections being disposed in coVering relation to said body;and means for supporting said covering sections, said means embodyingcross members extending across said body, one of said members forming abridge disposed at the center of said body to engage the ends of saidsections to prevent the lift thereof above-the level of said body, saidmeans further embodying a plurality of cover sections separated to formslats or braces extending across said body and arranged for theinterweaving of said covering abrasive sections.

3. A pencil sharpener comprising a boxlike body; a cover surroundingsaid body for covering the sides thereof, said cover ,providing a spacebetween the ends thereof and the ends of said body; a resilient sheet ofabrasive bent to form angularly disposed sections, one of said sectionsclosing the top of said body and the other section being held betweensaid body and said cover in the space provided therefor for supportingthe firstmentio ned section in covering relation to said body; and abridge member extending across said body for engaging the free end ofsaid first-mentioned section to limit the lift thereof.
